Having little or no hair.
The hairless cat is known for its unique appearance.
Hairless → It is formed from "hair" (from Old English "haer", meaning the fine strands growing from the skin) and "-less" (meaning without). The word "hairless" means without hair or lacking hair.
Think of being 'without' ('-less') 'hair' — that's why hairless means lacking hair.
